Description
Technical field
The present invention relates to the production line of caused by spinning industrial production, particularly to fabrics printing and dyeing pre-treatment desizing, concise and
Bleaching line, and printing and dyeing production pre-processing device.
Background technology
Dyeing is main industries preferable, time-honored largest in China's textile industry, basic, in China
There is the developing history of last 100 years.Dye material kind and quantity that dyeing uses are most.Due to printing and dyeing kind contain a large amount of
Natural impurity can affect the quality of following process process and product, needs to use chemical method to be removed.
In prior art, the process of scouringing and bleaching of textile dye transfer pre-treatment includes desizing, concise and bleaching three process.
When weaving, owing to opening and the effect of throwing a spear are by bigger tension force and friction, often there is cracked ends phenomenon in warp thread, for
Minimizing cracked ends, improves the strength of warp thread, wearability and smooth degree, it is ensured that weaves cotton cloth is smoothed out, warp thread one before weaving
As will process through starching.The convenient weaving of warp sizing, but bring many difficulties to dyeing and printing process, it not only affects fabric
Permeability, obstruction chemical agent and dyestuff contact with fiber, and consume contaminates chemical medicine product more, also can affect product quality.So
Cotton is desizing to be carried out before scouringing and bleaching.Slurry on the most removable cotton of desizing, and the part sky on cotton fiber can also be removed
So impurity.
Cotton is after desizing, although major part slurry and fraction natural impurity have been removed, but remain
Major part natural impurity, such as waxy substance, pectin substance, nitrogen substance, cotton seed hulls and part oil preparation and a small amount of slurry etc., these
The existence of impurity makes that bafta cloth cover is more yellow, poor permeability, it is impossible to meet the requirement of the following process such as dyeing, stamp, arrangement, because of
This, kiering to be carried out after desizing.Kiering is exactly chemically to remove the natural impurity on cotton, the mistake of concise purification cellulose
Journey.
Cotton is after kiering, although eliminating impurity, but still residual pigment to a certain extent, dirty appearance is white,
Impact dyeing and the colour brightness of PRINTED FABRIC, therefore need to bleach.The purpose of bleaching mainly removes natural pigment, composes
Give the cotton whiteness with necessity, other impurity of residual on cotton can also be removed simultaneously further, improve its wettability.
At present in textile dye transfer pre-treatment, desizing, concise and bleaching three process are respectively during three independence
Complete.The shortcoming of this technique is: operation is complicated, equipment flowing water line length, energy consumption big, and the activity duration is long, containing big in working solution
The Caustic soda of amount, bleach, stabilizer etc., waste discharge toxicity is big, and environmental pollution is serious, and intractability is high.
Current existing on a small quantity to desizing, the concise and production line of bleaching three process merging, by desizing, concise and bleaching phase
In conjunction with, reduce processing link, energy-saving and water-saving, save people laborsaving, improve working (machining) efficiency, but contain substantial amounts of burning due to working solution equally
Alkali, bleach, stabilizer, there is also the situation that waste discharge toxicity is big, environmental pollution is serious.
